D975XBX - E6600 - XFX 8800GTX - OC setup

I have OC'd my system and will post the specs here and was wondering if someone can tell me if this sounds like a good stable setup or did I miss something.

SYSTEM:

DVD - LG DVD+/- everything light scribe yada yada yada (never going to burn a thing on it)

Sound - SB X-fi Fatal1ty not OC'd in last PCI slot

MB - D975XBX v.AAD270904-306, 20% OC, MB 41C, Case 40C, Bios 1476

MEM - OCZ2G8001G X 2 = 2GB @ 400MHz 5-5-5-15, 1.9V, FSB/DRAM 4:5

Video - XFX 8800GTX, Stock not OC'd (yet) ruining ~63C (WOW! HOT!)

CPU - C2D E6600 @ 2880MHz, Bus 320MHz, Multiplier 9, FSB 1280MHz, 1.213V, Standby temp 46C, 100% both CPUs 66C

The system is stable and the CPU fan only spins up when running 100% on both cores (using Intel tat.exe). Over-temp does not at this time (winter) appear to be a problem. The CPU is cooled by the retail box air cooled fan. There is a 120mm case fan (Flow IN) on the {Raptor 74GB HD, one for XP and one for Vista (only using/connecting one at a time)}. There is a 120MM case fan (Flow OUT) on the back and a 120MM fan (Flow OUT) over the CPU. Power supply has fan speed all the way up and I did not adjust any of the voltages from factory spec. The case is a mid tower sealed tiger direct $19.99 special (I know I know I just could not see spending another $100 on a case that will in 6 months be collecting dust in the basement) with a modified 120mm fan over the CPU.

I choose these settings to get the DDR2-800 running at 400MHz while overclocking the CPU and hopefully not effecting the rest of the system. Does this make sense? or would I be better off under clocking the MEM and going for a higher CPU clock and risking higher temps?

What would be the next logical step if I wanted to take it to the next level and would it be worth it?

Would it be safe to push the bus further? Go to 30% instead of 20%, that would over clock my RAM as well, does anyone know if it can handle it?

OK, I upped my bus to 25%, temps went up about 2C. I am now running @ 3001.8MHz, Bus-333.5MHz, Multiplier - 9X, Rated FSB - 1334.1MHz. Memory = 416.9MHz still 5.5.5.15 @ 4:5 ratio. All is well and 3d Mark score is 10648, is this good? According to 3dMark I scored very low for my setup (like the bottom 10%), what could be wrong?

10000 should be norm

The RAM should be fine, but if it craps out just up the voltage a notch and try again. Anything up to 2.2v should be absolutely fine.

If you want to improve your OC further the go for another cooler. I have this:

Cheap but good. The retail version of this has for some reason shot up to $60!?!

Not sure about the 3DMark score..... I haven't used it before, I use PC Mark, and that gives you a breakdown of your score that you can compare with competitors, to identify your system's weaknesses.

I don't believe there are any after market coolers out yet, for the 8800 series cards.

Is your memory base clock 533MHz or 800MHz? Did you flash your mobo with the latest BIOS? I believe the older BIOS of D975XBX only runs 533MHz. My highest 3DMark06 scores with D975XBX2 (BIOS 2431 from 1/10/07) and C2X6800 OC'ed to 3.6GHz and XFX 8800GTX was 11828. I was running Corsair TWINX2048-6400C4D at 4-4-4-12 at Bus 300 MHz, 12 Multiplier. So you see, my 3DMark06 scores is not much higher than yours. So I think your 3DMark06 scores are fine for the speed you're running.

BTW, you got a good batch of E6600 for the voltage and temps you need to set for the OCing. Just curious, what's your batch ID?

Please disregard my first question about your mem base clock. I must have overlooked you post. Again, your 3DMark06 is not bad at all for that speed. You said your 3DMark06 scores are at the bottom 10% but what are the speeds of the other systems with scores higher than yours? They're not running 3GHz, aren't they?

OK, I ordered one from ebay. Saved me the tax;

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=013&ss...

They also did not have one in stock at microcenter (Woodridge, IL). I saved like $3 ordering it on e-bay with a buy it now and did not even have to leave the house. There are 19 of them left on e-bay get them while their hot! the List price is now ~$60 but only $26 + SH on e-bay (see link above)

The other 3DMarks were like 16K, I wonder if people are not fudging the numbers with some trick. How do I check the CPU batch number, with CPUz? I am at work and cannot check it until tonight. I am going to see if I can get a RAM cooler and rock my OCZ with a 30% OC 4:5. If I try to drop the timings below 5-5-5-15 say 5-5-5-12 the system hangs in XP. I plan to get another 2GB of the same ram due to VISTA hogging 900MB for the OS, its SICK! I should get a better case too, perhaps a tower with tons of fans. I don’t want to go to liquid cooling cause of the expense and all the what ifs!

3DMarks 16K is only possible with dual 8800GTX (2 x 8800GTX running in SLI mode). I don't think you can get 16K with a single card.

No, I don't think anybody can fudge his 3DMark06 score because those are saved in an offical database maintained by FutureMark Corp. At least, they're not supposed to let people fudging around with it. They even refuse to accept your 3DMark scores if you are running with the latest graphics driver obtained from NVidia but not validated by FutureMark (such as Beta driver)

Mate I'm interested in this as my spec is uncannilly identicle to yours. I just scored 13302 (and I only have 1 gb at the moment), with no overclocking whatsoever. you got something going wrong there.

e6600 stock cooling
gainward 8800gtx
1gb crucial ballistix
74gb 10,000 rpm raptor - sata(plus storage drive, irrelevant)

Wow, mate you have one of the top 3DMark06 scores I've ever seen with a single non-overclocked 8800GTX. May be your Gainward 8800GTX is much better than my XFX 8800GTX?
BTW, OCing the CPU will not increase the 3DMark06 scores as much as OCing the GPU itself. Are you running 3DMark06 version 1.1.0 or 1.0.2?

X6800 OC'ed to 3.6GHz
2GB Corsair Dominator DDR2-6400C4D, Timings 4-4-4-12
150GB WD Raptor

I am running 3dMarks06 1.1.0 and my score is 10667 or so. I will see if I can find 3DMarks05 1.1.0 and run the test.

CPU = 65nm, 1.213V, running core: 3001.8MHz, Bus: 333.5, FSB:1334.1, Batch: L628A270, Version: D63625-001, Package date: 8-23-06, 1.35V Max

Memory = 416.9MHz, 4:5, 5-5-5-15

A HA! I did some research and found that my 3dmark06 score is really not that bad! I should be getting ~1100 for my setup and have seen as high as 11761 (P5N-E SLI motherboard) I almost got that motherboard :( 

Anyway When my new cooler gets in I am going to crank up the clock some more (perhaps bump CPU voltage a little) Overclock the 8800GTX to 108/378MHz (if it will do it) and let the memory sizzle with a ~80mm fan over it and check my scores again. The figures of 16K were Quad CPU systems running SLI, why the heck would 3dMarks06 compare my C2D non-SLI with a quad core SLI system in the conclusion screen? Unfair! anyway I am only a little under par with most E6600 8800GTX systems. A few more tweaks and I should up in the 1100s! I will run the test again with everything shut down including mouse and N52 drivers.

Thechevron - I got 13693 on 3dmark05 1.3.0 an I have not OC'd my GPU yet
February 7, 2007 2:23:49 AM

Well I could not wait! I OC'd my XFX 8800GTX! :twisted:

I was not able to reach a stable GPU: 650MHz, Video Ram: 1000MHz That I should have with this card (you win some you loose some :cry:  ) I then tried these combinations with lock ups each time: 652/980, 640/1000, 620/990.

I then tried 610/990 and VOILA! stable system! :D  3DMark06 came in as 11059!! YES in the 1100s! WOOT! Not sure why the GPU was halting on the higher clocks, guess that's all it can do. I think I can run the video ram at 1000MHz but I need to run some stability tests over night at 610/990. Also I don't think the overclock settings are stored when you shut down :(

Got my freezer Pro 7 CPU cooler, WHAT A DIFFERENCE! the case does not even get hot anymore! CPU running 45C with 64C max load. I can only clock to 3.2GHz any faster and system will not boot, tried 3.6GHz but no good, I could bump the CPU voltage but dont want to risk it with this MB. My 3Dmark scores with 8800GTX overclocked 620MHz core and 1000MHz mem I get a 11698 score in 3dmark06. That's good enough for me, When I get the eVGA nforce 680 board I should be able to do more. Had to upgrade Vista 32bit to 64bit due to 4GB addressable memory locations after I added another 2GB of ram. Vista 64bit can see all 4GBs and the ~750MB of the 8800GTX and the 64MB in the sound card. I have been playing Vanguard on this system with 16XAA and all features to max and no problems in Vista 64. It does help to turn off the gadget bar before starting the game. Thanks for everyone help, I think I got my system where I want it.
